Any recommendations for slim leg or skinny jeans suitable for ample bum but small waist? I loved Levis Curve ID but they've been discontinued, and most jeans I've tried on gape at the waist or fall down when I bend over or squat (which is frequently, with a toddler). I am tall and slim, but with an ample behind. Currently wearing some M&S high-waisted hand me downs from my mum - help!
